LOCOMOTIVE.

Specification of Letters Patent.

Patented J an. 4, 1916.

Application filed August 20, 1914. Serial No. 857,719.

To all whom z't-may concern:

Be it known that I, WILLIAM F. KIESEL,

My invention relates to electric locomo-- tives and more particularly tothe construction and arrangement of the pony trucks thereof.

. The invention has for one of its objects to provide means whereby the load on the truck is carried at three points, thus giving a three point suspension, together with means for attaching a brake mechanism thereto for the purpose of increasing the braking safety factor of the locomotive to which it is applied.

Another of the objects is to provide a practical method of weight equalization whereby the weight of the locomotive carried by the pony truck is transferred not only to the journal boxes of the said truck but also to the journal boxes of the main drivers of the locomotive through an equalizing beam and spring arrangement.

The above and other objects, and the novel features of my invention will be apparent from the following description,

taken in connection with the drawings, in

. which Figure .1 is a central longitudinal sectional view of the forward end of the locomotive truck, the cab thereof being shown in outline; Fig. 2 is a top plan view of a pony truck constructed according to this f-invention; Fig. 3 isa transverse cross-section on the line 33 of Fig. 2; and Fig. 4 is a side elevation of the pony truck.

Referring to Fig. 1,- 10 and 11 designate the forward main driver shafts or a-xles which have pairs of wheels 12 and 13 fixed thereto at the end of the axle.

The axles also support suitable journal boxes 14 upon' springs 21 by means of links 22 which are pivoted to the side frame member 20. The sprmgs 21 each consist of a plurality of superposed fiat spring plates tied together by a band 23 and fulcrumed at the upper end of the bracket 15 which rests on the journal box 14.

Equally distant from the driver axles 10 and 11 are two pony truck axles 24 and 25 whlch have pairs of pony truck wheels 26 and 27 fixed thereto on the ends thereof.

The pony truck frame 28 is shown in Fig. 2, and consists of a single casting substantially in the shape of the letter A, the cross bars 29 thereof representing the tran som bars between which a pair of

transverse springs

30, 30 is hung. The

springs

30, 30 each comprise a series of superposed fiat spring plates tied together by bands 31, the tops of the bands extending above the upper edge 32 of the adjacent part of the truck frame. vThe bands 31 carry the truck bolster casting 33 upon which rest the angle plates 34 which are riveted to the- .inside of the side frame members 20 of the truck. It will therefore be observed that the weight carried by the truck is transferred from the locomotive frames to the truck springs 30 through the truck bolsters 33.

At the ends of the

cross bars

29, 29 of the pony truck frame and near the outside edge of the frame there are cavities 35 open at the bottom and top and separated from the spring opening 36' by cross members 37. The pair of springs extending into the spring compartment 36 is supported at its lower side by cross-bolts 38 which are hung from the links 39, 40 and 41. The link 40 is thicker than the outside links 39 and 41 and is disposed between the ends of the two springs. The links are each T-shaped, having a head 42 disposed in the cavity 35. The lower opening 43 in the cavity is of smaller size than the head 42 of each link whereby the links will be retained in place, should the primary supporting means fail, by the shoulder 44 thereof engaging the ledge 45 at the bottom of the cavity. The primary supporting means for each group of three links at the ends of the springs comprises a pair of cross bolts 46 and 47 which extend through openings in the head 42 of each of the links and have their ends resting on ledges in the cavity. Brackets 48 and 49 are .hung from the cross members 29 and pass under the springs 30, being spaced therefrom and serving to hold up the springs in case the bolts 38 or any of the spring hanger links or parts fail.

Brackets and 51 are formed integral with the frame and are located outside the cavities 35 on the transverse central line of the truck frame. The

brackets

50 and 51 extend upwardly above the surface 62 and have spaced

parts

52 and 53 to receive between them the upper end of a brake lever 54 which has 1pivoted thereto the brake head 55 carrying t -

mernbers

52 and 53 have co-axially arranged holes 57 drilled therein to recelve the pin 58. whereby the brake levers 54 may be pivotally secured to the brackets. slots or spaces 59 in the brackets are so positioned that the brake hangers and brake heads. will be located directly in line with the Wheels 27 of the truck.

The legs 60 and 61 of the truck frame are parallel and have

journal boxes

62 and 63 at their ends to fit the axle 25 whereby the frame is rockably supported at two points on the said axle between the wheels 27. I

As will be seen from an inspection of Figs. 3 and 4,, the frame 28 has converging parts at one end and is of open-work construction and has front and rear

inclined bracing members

64 and 65 joined together byhorizontal bracing members 66 which are connected to the main horizontal portion 67 of theframe by vertical bracing parts 68. The top 69 of the frame has a spherical socket 70 in its lower side in which fits the hemispherical ball member 71 located near the lower end of a vertical hanger rod 72. The hanger rod 72 extends through guide sleeves 73 located on opposite sides of the top end 69 and held in position by bracket members 74 connected to the main side members 20. The pony truck frame has an opening 75 therein through which the rod 72 extends upwardly where it is pivotally connected by va link 76 near the center of a cross beam or bar 77 which is supported at its ends on the opposite ends of the springs from the links 22.

The main driving springs 21 positioned above the journal boxes of the main drive axles 10 and 11 constitute a spring equalization and transfer the weight of the locomotive and frame 'to the main drive axle. weight of the locomotive and frame, supported by the transverse springs on the pony truck 1s partly transferred to the pony truck axles at two points and partly transferred to the main driver springs at one point and from them to the main driving axles, thereby efiecting a three point suspension of the weight carried by the pony truck frame.

While I have shown and described my invention in detail, I do not wish to be limited to the exact construction shown and described as t is evident that numerous e brake shoe 56. The spaced The The-
